Answer:
a = 240
Step-by-step explanation:
To solve for a, divide 48 by 0.2:
0.2a = 48
a = 48 / 0.2 = 240
Answer:
Simplifying
0.2a = 48
Solving
0.2a = 48
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by '0.2'.
a = 240
Simplifying
a = 240

Find the volume of each figure, round to nearest tenth
Answer:
These are the answers
Step-by-step explanation:
The volume of a sphere formula is:
V = 4/3 x pi x r cubed
V = 4/3 x 3.14 x 6 cubed
V = 4/3 x 678.24
V = 4/3 x 678.24/1
V = 2712.96/3
V = 904.32 cubic cm
So 904.30 cubic cm would be the volume.
the radius is 6
the diameter is 12
and i am guessing the height is also 12 since a sphere is perfectly round

Solve 4(x + 2) = 20
PLEASE GIVE A STEP BY STEP ANSWER NOF HOW YOU GOT IT
WILL MARK BRAINLEST
Answer:
x = 3
Explanation:
[tex]\sf 4(x + 2) = 20[/tex]
[tex]\sf 4x + 8 = 20[/tex]
[tex]\sf 4x = 20 - 8[/tex]
[tex]\sf 4x = 12[/tex]
[tex]\sf x = \frac{12}{4}[/tex]
[tex]\sf x = 3[/tex]
check:
4(x + 2) = 20
4(3 + 2) = 20
4(5) = 20
20 = 20
Hence proved x = 3
Answer:
x=3
Step-by-step explanation:
Subtract both sides of the equation. Simplify, Divide both sides of the equation by the same term. And then Simplify
Darrin tosses a quarter and a penny 20 times. He gets heads on both coins
twice. Compare the theoretical probability of getting heads on both coins
with Darrin’s experimental probability of getting heads on both coins. Why
might the probabilities differ?
Answer:
The 4 possible outcomes are HH, HT, TH, TT.
So theoretically, HH should occur 1in 4 times.
1/4 = x/20
x = 5
So why is it actually 2 in 20 when theoretically it should be 5 in 20? One reason is that theoretical probabilities gain more accuracy with larger numbers of results (e.g tossing the coins 100 times). You can likely think of some more reasons.

Step-by-step explanation:
Find the product and write the answer in decimal form.
(6.5) (2 4/5)
The product of (6.5) and (2 4/5) is 91/5 and after converting in decimal it is approximately 18.2.
To find the product of (6.5) and (2 4/5), we need to convert the mixed number into an improper fraction.
First, we convert the mixed number 2 4/5 into an improper fraction:
2 4/5 = (2 × 5 + 4)/5 = 14/5
Now, we can multiply 6.5 by 14/5:
(6.5) × (14/5) = (6.5 × 14)/(1 × 5) = 91/5
To get the answer in decimal divide it further: 91/5 ≈ 18.2
Therefore, the product of (6.5) and (2 4/5) is approximately 18.2.

https://brainly.com/question/30774653
The product of 6.5 and [tex]2 \frac{4}{5}[/tex] is 18.2 in decimal form
1. Converting the mixed number to an improper fraction.
[tex]2 \frac{4}{5}[/tex] is equivalent to [tex]\frac{2*5+ 4}{5}[/tex], which simplifies to [tex]\frac{14}{5}[/tex].
2. Multiplying the decimal and the improper fraction.
6.5 × [tex]\frac{14}{5}[/tex] can be calculated as [tex]\frac{6.5 * 14}{5}[/tex].
3. Performing the multiplication.
6.5 × 14 = 91.
4. Simplifying the fraction.
[tex]\frac{91}{5}[/tex] is already in its simplest form.
5. Writing the answer in decimal form.
Divide 91 by 5 using long division, and we get 18.2.
Therefore, the product of (6.5) and ([tex]2 \frac{4}{5}[/tex]) is 18.2 when expressed in decimal form.
The concept of multiplying a decimal number and an improper fraction is used in this question.

How many different 4-digit numbers can be created if no digit can be
repeated? Remember, a number cannot begin with 0.
Answer:
2
Step-by-step explanation:
1234
4567
Explanation:
There are ten single digit values 0 through 9. But we cannot use 0 as the first digit, so we have 9 possible choices for the first slot.
For the second slot, we also have 9 choices because we can now pick 0.
The third slot has 8 choices.
The last slot has 7 choices.
Each time we form a new slot, the number of choices drops by 1. The exception of course is the jump from the first to second slot.
Overall, there are 9*9*8*7 = 4536 different numbers.
